Industrial Noise and Vibration Control The main purpose of industrial noise control is to protect the hearing of the people working in the production units, factories and workshops etc. Noise generated by fluctuating forces in structures...The internal forces in a machine are transferred as structure-borne sound to the surface where it is radiated as sound...The forces can be either steady, caused by reciprocating motion in an engine, or transient caused by impacts. ..More noise is produced if a task is carried out with great force for a short time than with less force for a longer time...Since the structural vibration will have to radiate as sound from the machine surfaces reduction of the surface area or reduction of the radiation efficiency of he surface can be good noise control techniques...An object with a small surface area may vibrate intensely without a great deal of noise radiation. The higher the frequencies, the smaller the surface must be to prevent disturbance
